These kinds of sets of problems can be fun and hard to solve at the same time. But for us to help out more data is needed. First is whether the shaking was happening prior to the work done. Just because one doesn't notice a problem does not mean it's not happening. We humans tend to attach "the inception" of a problem to the moment we discover it. Many problems have been going on for a while but not yet perceived by the rider, I might say most problems lay hidden but "active".


So out of balance wheels spinning can cause hop/shake on a stand where the mass of the wheel is a significant portion of the system's and where the stability of the bike is less then when on the road. This problem is easily solved or at least played with by attaching tiny weights (solder wrapped around a spoke nipple) or removing weights like reflectors.


Hub bearings are another source of shake/wobble in a spinning wheel. From very loosely adjusted bearings that allow much hub/wheel slop about the axle in a rather inconsistent manor to a very rhythmic manor when a hub bearing has one too many balls in it. This over filled with balls bearing will have it's rotation happen in two axises at the same time. One is the rim revolving about the axle and the second is the off set between the bearing's inner and outer surfaces that cocks the hub askew from correct. But as the rim is rotated around the axle this offset/askewness also rotates at about half speed compared to the wheel. So in in a bike this condition looks like the rim is out of true yet the out point is shifting about the rim's circumference. I don't know what form of bearings your hub has so I don't know if this too many balls are even a possibility.


Was anything else done to the bike or wheel when the freehub body work was done? Like a tire being remounted or tube changed? Can you see any actual rim/tire run out (laterally or radially), is it consistent?


As to the catch or stickiness- Hubs can be odd things especially if radial contact cartridge bearings are used. Very small dimensions can have big effects on things. Many of the cartridge bearings used in bike parts really want a tad of end play to not wear rapidly. The problem is that the bike industry hasn't completely tooled up to control the few thousandths of an inch which can be the difference between good function and sloppy or tight. Add in that many freehubs use simple "o" ring like seals which might be unlubed or too compressed to allow free spin before the break in period is done.


Of course that other then wheel problems are causing the catch. No brake pad or frame rubbing. Andy.
